Subject Re: PySpark issue with sortByKey: "IndexError: list index out of range"
Date Thu, 13 Nov 2014 19:28:43 GMT
Thanks for the thoughts. I've been testing on Spark 1.1 and haven't seen
the IndexError yet. I've run into some other errors ("too many open
files"), but these issues seem to have been discussed already. The dataset,
by the way, was about 40 Gb and 188 million lines; I'm running a sort on 3
worker nodes with a total of about 80 cores.

Thanks again for the tips!
